Control Locations
The ACS 400 drive can receive control information from multiple sources, including digital I/O,
analog I/O, keypad, and Modbus fieldbus.
To control the ACS 400 via the serial communication channel 1 (Modbus fieldbus), it must be
pprogrammed to accept control commands and/or frequency references from this channel. In
addition, ACS 400 must be in remote control.
The necessary parameters and their usage are listed in Table 15. Note especially, that before any
control commands can be given through serial communication channel 1, parameter 5006
COMM
COMMANDS value must be set to STD MODBUS.
Further information on all the parameters and their alternative settings is given in “ACS 400
Complete Parameter List” on page 65.
